xilinx: common: Add support for partial string match in board_fit_config_name_match()

Board name in FIT image can use U-Boot regular expressions SLRE to instruct
U-Boot to handle all revisions for certain board.
For example when name (description property) is saying "zynqmp-zcu104-revA"
only description with this name is selected.
When zynqmp-zcu104.* is described then all board revisions will be handled
by this fragment.
Xilinx normally have some board revisions which are SW compatible to each
other. That's why make sense to define board name with revisions first
follow by generic description with '.*' at the end like this:

config_1 {
        description = "zynqmp-zcu104-rev[AB]";
        fdt = "zynqmp-zcu104-revA";
};
config_2 {
        description = "zynqmp-zcu104.*";
        fdt = "zynqmp-zcu104-revC";
};
